Abstract
The utility model discloses a tractor front driving device with a disc type brake. At present, most of tractors only adopt an independent rear wheel brake mechanism, when the tractors drive on a rough and steep road in hilly and mountainous areas, the tractors are easy to have an accident owning to the disadvantage of a braking performance, besides, as a driving shaft has high torque force, the driving shaft is easy to facture, so as to cause life risk and property loss of a driver. In the utility model, the types of a front driving shaft and a driving shaft shell of the tractor are changed, the original front driving shaft integrating driving and supporting is changed into a front driving shaft and a half shaft sleeve pipe, which have different functions, a front wheel brake device is additionally arranged, the situation that the traditional tractor is easy to have a safety problem is overcome, and the safety performance of the tractor is improved.
Description
Technical field
The utility model relates to a kind of trac. front driving device, and especially a kind of trac. front driving device of tep reel formula drg, said trac. comprise walker tractor transportation unit or hand-variable transport plane.
Background technology
Walker tractor transportation unit or hand-variable transport plane relatively are applicable to the small freight transportation under the road conditions poor condition such as rural area, mountain area, forest zone and mine, are friend's peasant good assistants.Existing most of trac.s only adopt independent trailing wheel stop mechanism; When trac. is steep with the slope at rugged road, the road is sliding road traveling; Because accident appears in the defective of deceleration and stopping performance easily, be on the other hand because the torsion of axle drive shaft is excessive; Occur the situation of axle drive shaft fracture easily, these two kinds of situations all can cause the life danger and the property damage of chaufeur.The present scheme that the problem of these existence is solved is exactly to strengthen the diameter of axle drive shaft, and this has just directly increased cost, is not the good method of dealing with problems, and braking does not all have desirable solution all the time to trac..Therefore, for improving the safety performance of trac., seeking a kind of desirable braking is necessary with the device that safety combines.
Summary of the invention
The purpose of the utility model; Just provide a kind of trac. front driving device of tep reel formula drg; Through increasing axle tube and front wheel brake device; Increase the safety performance of trac., solved traditional trac. under abominable road conditions, occurred the safety problem that braking is bad and the axle drive shaft easy fracture causes easily.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is following: a kind of trac. front driving device of tep reel formula drg; Comprise the walker tractor transmission assembly; Be fixed on the before driving axle housing on the transmission assembly, on the before driving axle housing, installing and fixing axle tube, axle tube also is connected to form an integral body with a brake-caliper support that brake cylinder, brake clamp are installed through fastener; Axle tube is equipped with wheel hub and brake disc through hub bearing, and wheel hub and brake disc can rotate around axle tube; Be fixed on two friction linings on the brake clamp and lay respectively at the both sides of brake disc, receive the interaction energy of brake cylinder to press to brake disc.
Take the utility model of above-mentioned measure; Changed the pattern of trac. drive axle and driving shaft shell; The pattern that original drive axle collection is driven and is supported for one resolves into drive axle and two function various parts of axle tube; Semiaxis fracture suddenly can not cause safety problem yet even under rugged abominable again road conditions, go, and improves the safety performance of trac.; Because the utility model has increased front wheel brake device, braking is sensitiveer, has overcome the defective of traditional trac. poor stop, thereby has realized the travel safety of trac. simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the utility model structural representation.
The specific embodiment:
The actuating device of trac. the right and left and the structure of wheel are the same, in order more clearly to describe the structure of the utility model, at this monolateral front driving device and brake equipment are described.
Fig. 1 is the structural representation of the trac. front driving device of a kind of tep reel formula of the utility model drg; Before driving axle housing 1 is fixed on the gear box of tractor assembly 3 through thru-bolt 2 shown in figure, and axle tube 4 uses thru-bolt 5 to be connected with brake-caliper support 6 with before driving axle housing 1.Tire 7 is installed on the steel ring 8; Steel ring 8 is installed on the wheel hub 9, and brake disc 10 adopts bolt 12 to be fixed on the wheel hub 9, between wheel hub 9 and the axle tube 4 hub bearing 11 is installed; Comprise that like this tire 7, steel ring 8, wheel hub 9 and brake disc 10 can be around axle tube 4 rotations; Drive axle 13 can be rotated in axle tube 4, and drive axle 13 wheel hub 9, the rotation of the rotating band runner hub 9 of drive axle 13 through semiaxis flange 14 captive joints.Thereby axle tube 4 also plays the effect of supporting trac..On before driving axle housing 1, be mounted with brake-caliper support 6; On brake-caliper support 6, be mounted with brake clamp 15 and brake cylinder 16; Be fixed with friction lining 17 in the both sides of brake clamp 15; Brake clamp 15 is exerted pressure to brake disc 10 under the effect of brake cylinder 16, the brake disc 10 of rotation is slowed down rotate even stops.Because brake disc 10 is to rotate synchronously with tire 7, steel ring 8 and wheel hub 9, therefore, when brake disc 10 slowed down velocity of rotation even stops, tire 7, steel ring 8 and wheel hub 9 also slowed down rotation synchronously even stop.This has just played the effect of braking.
The utility model is work like this: when trac. was walked, engine power was passed to drive axle 13 through gear box of tractor assembly 3, then successively through semiaxis flange 14 → wheel hub 9 → steel ring 8 → tire 7, thereby drove the trac. walking.Be that wheel hub 9 rotates with tire 7 with brake disc 10, brake cylinder 16 is fixed on the brake-caliper support 6.Be installed in the both sides that two brake clamp friction linings 17 on the brake clamp 15 lay respectively at brake disc 10.When chaufeur is stepped on brake pedal; Promote the master cylinder piston of master brake cylinder through push rod; Make master cylinder inside brake liquid under certain pressure, flow into brake cylinder 16; The hydraulic action that the piston of front wheel brake wheel cylinder 16 is transported by oil pipe, two brake clamp friction linings 17 that promote on the brake clamp 15 are pressed to brake disc 10 generation friction brakinges.When loosen the brake, two brake clamp friction linings 17 on the brake clamp 15 reset, and friction moment and braking force disappear, and brake action stops.
